# How do you simplify 4div 0.5?

Jul 23, 2016

Take a look at the explanation.

#### Explanation:

$4 \div 0.5$ or $\frac{4}{0.5}$ can easily be simplified. Think of it this way: if you were to divide 4 slices of pizza in half, how many slices would you then have? Remember, $0.5$ equals $\frac{1}{2}$.

$1$ slice cut in half would equal $2$ slices. So you can think of this as a multiplication question as well. If $1$ slice cut in half equals $2$ slices, then $4$ slices cut in half would then equal how many slices?

• $4 \cdot 2 = 8$

Or, you can think of it this way. How many "half " slices would it take to make $4$ whole slices?

$0.5 + 0.5 = 1$ slice
$0.5 + 0.5 = 1$ (now $2$ slices)
$0.5 + 0.5 = 1$ (now $3$ slices)
$0.5 + 0.5 = 1$ slices (now $4$ slices)

It would take a total of $8$ half slices to make 4 whole slices. So $4$ divided by $0.5$ equals $8$.

$4 \div 0.5 = 8$
